  • The Xodus ISO gets a total makeover in the latest iteration that it can be classified as a totally new shoe. Without a doubt, the most obvious changes are readily found in the upper. In this version, the changes in the upper dictates the new name of this shoe. The new upper technology gives a more comfortable, precise, and lightweight fit. For good measure, this version has water-repellent upper that keeps the foot dry during drizzles or early morning runs on grass or dead leaves.
  • The outsole of the Xodus ISO Runshield replaces the Vibram with Saucony’s proprietary PwrTrac technology. Saucony made the change to enhance durability, ground feedback, and a little torsional bend. It gives the shoe better cushioning as well as the outsole slightly compresses upon impact.
  • The last major change in this shoe is the introduction of the Everun top sole, which gives the midsole substantially more durability and responsiveness. It also gives the shoe an improved performance for long distance running because of this new feature.

The Runshield model of the Xodus ISO offers a standard fit to runners. It has a really good heel and midfoot hold that is by no means constrictive. The forefoot god enough space to be comfortable without being sloppy. It is the type of fit that generally accommodates different foot widths. The shoe runs true to size.

Saucony’s PwrTrac rubber compound covers a large part of the outsole for a blend of traction and durability. Most notable in the outsole layout are deep zigzag lugs in the middle of the outsole. It definitely helps with the grip on varied outdoor surfaces. At the perimeter of the shoe are large and arrow-shaped lugs that face opposite directions. The design makes uphill or downhill moves easier to handle. Saucony uses this outsole configuration as this has a more forgiving compression, which aids slightly the cushioning and shock-absorbing abilities of the shoe.

Saucony unveils the Everun technology as the top sole of the Xodus ISO Runshield. It is noted as having more durability and responsiveness than any of the midsole technologies currently offered by the company. This sits on top of a regular EVA, which by itself has decent cushioning and responsiveness.

The upper dictates the performance, feel, and fit of the Xodus ISO Runshield. As the Runshield technology is known for, the upper is coated with DWR material, which is extremely resistant to water. The lightweight support is made possible by the ISOFit construction of the mesh. These overlays are tied to the laces and greatly helps with the security and support in this shoe. Trail protection comes in the form of the Molded Toe Shell or a relatively thick rubberized material that prevents the toes from getting bruised. A gusseted design keeps the tongue in place and keeps debris from easily getting inside. Enhanced comfort is provided by the ComforLite Sockliner, which is also utilized for its anti-odor and anti-microbial properties. The Rundry lining around the ankle collar wicks moisture away and ramps up the step-in comfort.
